JOSEPH ROS-SI. OF PEETZBURG, NEW JERSEY.

ASH-SIFTER.

Application filed August 12, 1918.

To all whom it may concern:

7 Be it known that I, JOSEPH RossI, a citizen of the United States, and a resident .01" lcetzburg, in the county of Bergen and t t-ate of New Jersey, have invented a new and improved Ash-Sifter, of which the following is a full, clear, and exact description.

The present invention relates more parties ularly to improvements in the construction and arrangement of parts forming the dustless ash sitter for which an application for patentbearing SerialNo. 232,373 was filed by me May 3, 1918. For a further under standing of said construction and assembly, cross reference is here made.

Among the objects which thepresent invention has in view are to reduce'the cost of construction of the apparatus, to facilitate the einptying'of the recovered coal, and to simplify the construction.

Description.

As seen in the drawings, a boxlike casing 10 has out-turned sliding rails 11 over which are curled channeled hangers 12. The hangers 12 are integrally mounted on a box drawer 13. The handle 14 thereon serves to manipulate the said drawer. One or more drawers 13 may be employed, it being preferred that at least two drawers should be used, one to receive the ashes from the drum 15, and the other, subsequently, to receive the remaining coal and clinkers.

The drum 15 has solid heads 16. Between the heads 16 a cylinder forming the body of the drum 15 extends. The cylinder is constructed of suitably open niesh wire Specification of Letters Patent.

Serial No. 249.451.

cloth. The drum and heads 16 thereof are carried on the shaft 17 which extends beyond the bearing plates 18 formed in the said heads, and at one end is furnished with a crank '19, the handle 20 whereof is employed by the operator for revolving the said druin. he plates 18 and bearings formed thereby are permanently secured in the ends of the casing 10. As distinguished from the invention to which cross reference has been made, it will be noted that the drum 15 in the present invention is permanently secured in the casing 10.

The casing '10 is coveredby a hood 21. The hood 21 is preferably seniicylindrical and has an outwardly folding edge 22 arranged to form the channel .for the upper edge of the casing 10, as best seen in Fig.

'5 of the drawing. The hood 21 has a feed opening at the top thereof which is normally closed by a slide 23. The slide 23 moves in channels formed by the up-set edges 24 and is furnished with a tab 25 by which said slide is engaged.

l/Vhen the slide 23 is open the drum 15 is rotated until the opening 26 is disposed in line with the opening exposed by the movement of the slide 23. The openin 26 is framed at each side by runner bars 2 The bars 27 are engaged by overturned edges 28 of a slide cover 29 which is moved to and from closure position by means of the tab 30 integrally formed thereon.

To facilitate the screening operation and to guide the ash and coal when being delivered from the drum, I provide two in; clines 31. The inclines 31 are best seen in Figs. 3 and 4. They consist of sections of screen material which are secured in position in the drum 15 at opposite ends thereof and converge upon the opening 26 at a relatively sharp angle. The inclines 31 perform a further function of distributing the ashes in the drum and breaking up or preventing massing or packing of the ash. The shaft 32 on which the drum 15 is supported cooperates to this end b shattering any mass which is thrown or dropped from the inclines 31 through the drum to the opposite side thereof.

When employing a sifter constructed and arranged as shown in the accompanying drawings and as above described the operation is as follows: The drum 15 is rotated until the opening 26 rests below the opening normally closed by the slide 23. The slide Patented Dec. 17, 1918.

is withdrawn exposing the slide 29, whichis then moved aside from the opening 26. The mixed ash and coal to be treated is now poured into the drum 15. When the drum is sufliciently charged the slides and 23. are closed. The operator now proceeds to rotate the drum 15 by employing at this end the crank 19 and the handle 20.

As the drum 15 rotates it is evident the inclines 31 passing to the underside of the drain receives the load of ashes thereon dust or free hyattrition the coal from the ash adhering thereto.

At the end or" a few minutes it will be found that the coal and coarser material which remain in the drum 15 have been cleared of all the ash usually adhering therei to. The drawer 13 in which the ash has Genie: at patent been received is then removed from the easing 10 to be replaced by a second drawer or by any suitable'receptacle for the coal or residue which has remained in the drunr 15. When this drawer or receptacle is disposed in position below the opening 26, the slide 29 is moved to its open position and the drum is revolved until the opening 26 Claim.

An ash sitter comprising a rotary sitter drum having a receiving and discharge opening therein; means centrally located in said drum for rotating the same; and a plurality of inclines permanently mounted in said drum to deliver the contents of said drum to said delivery opening, said inclines being constructed from open-mesh material go operate as a sitter for the contents of said ruin.
